要:基于城市流和连锁网络模型,构建了2000年、2005年和2013年中原经济区复杂产业网络的有向拓扑结构图模型,借助复杂网络相关理论和方法及PAJEK软件,分析了中原经济区复杂产业网络的结构特征和演化特征。结果显示:1中原经济区产业发展过程中存在一定程度上的"马太效应",网络呈现出无标度网络的"择优增长"特征。2郑州、信阳和邯郸在中原经济区复杂产业网络中具有良好的资源控制能力和重要的地位,网络水平发育不明显,产业网络密度偏小。3在中原经济区复杂产业网络中,产业度与产业集聚系数表现出反向关联,与介数中心性呈现正向关联。4中原经济区产业网络随着经济社会的发展朝着更加复杂化的趋势发展。
Based on the urban flow and chain network model, we established the directed topology graphs of industrial networks in this economic region for the years of 2000, 2005 and 2013, which including all sectors of primary, secondary and tertiary industries. By means of the complex networks theory and the software PAJEK, we analyzed the industrial networks in terms of the industry degree, the industry clustering coefficient and industry betweenness centrality, the evolution characteristics of the ring rate, the binding degree and the line point rate. There are several findings from the analytical results:1) There is "Matthew effect" in the Central Plains Economic Zone complex industry networks, while the networks presented a tendency of "preferential growth". 2) Zhengzhou, Xinyang and Handan have strong resources control ability and important position in the complex industrial networks, and exist strong industry relations with most of the other cities. 3) The structural parameters show some regularity in the complex industrial networks: there is a reverse correlation between industry degree and industry clustering coefficient, but the positive correlation between industry degree and industry betweenness centrality. 4) The network efficiency and network sophistication in the Central Plains Economic Zone decreased slightly in 2000-2005 and improved in 2005-2013.
